Are there any commercially available chemicals that can assist in Hydrogen Gas remediation? Thanks.

I don't know of anything commercially available. Hydrogen from electrolysis is usually ventilated to maintain hydrogen below explosion limits. Cheap, cheap, cheap. In cases where ventilation isn't suitable, hydrogen getters can be used but they are reactive and very expensive.
